Sharp RT3151 Electronic Tape Processor

A Sharp RT3151 cassette deck / electronic tape processor. Don't know what to say about this one, it's a most unusual device with an LCD pnale that shows date and time and various other things. I know that it works as a cassette deck but don't know how to test the rest so it's being sold as a collector's piece. It measures approx 440mm wide by 140mm high.
